Power generation is determined by measuring any two of the following Voltage (V), Current (I), or Resistance (R). With these measurements, the Power can be calculated with the appropriate formula from the formula wheel. The unit used for Power is Watts (similar to the units for Length can be Inches or Centimeters).

In the Wind Turbine Challenge 2.0 you will use the voltage and resistance measurements to calculate the Power your wind turbine blades are producing.

Using the equation P = V²/R and measuring Voltage and Resistance you will be able to determine the power produced.
